Lock nuts 39 and 40 are threaded on this shown in dotted lines in Fig. 4 and in Fig. 2. stud 31. The construction is such that upon This slide block 9 is formed V-shaped at its opsliding the block I! inwardly it may be locked posite longitudinal edges to provide the inclined faces 13 and I4 on one side and i5 and I6 on the opposite side. An adjusting block I1 is provided with a V-shaped groove on one side to provide the faces I8 and I9 which are adapted 2 to bear against the faces l3 and I4 respectively of the slide block 9. I A slide 20 is provided having the transversely extended T-slots 2| in which are fastened sein position by means of the lock nuts 39 and 4.0 and this inward sliding may be effected 'by loosening the nut 39 and threading the nut 40 to force the block I1 inwardly. As this block I! moves inwardly it will move laterally into closer on the slide block 29 will be upwardly and? there 1 will also be a lateral pressure on the depending portions 20a and 20b by virtue of their pressing action against the faces l3, M, [5, and i6. Likewise, when the presser plate, or V-block H, is used for exerting pressure; the pressure will be directed laterally and upwardly and downwardly. This makes it possible to lock the slide 20' in position without in any manner disturbing the position to which it may have been adjusted. Consequently, it is possible with aslide mounting of this class to adjust the slide to very fine adjusted positions; It will also be noted th'at the bearing surfaces provided are the areas of the faces; l3, l4, l5, and le against the corresponding faces in the portion 20b and inthe V-block l! which, in turn, transmits the pressure to the faces- 3|, 32, and 33'. Pressure will also be exerted on the face 45 so that a maximum area of contact isthus provided which is important in securing fixedly a slide on' its mounting and preventing a disturbance of" that adjusted position in which it may be secured What 15 claim is:

A device of the class describedcomprising a slide block having oppositely disposed side faces, each formed V-shape'd' in cross-section; a slide positionedover said slide block and having a 4 V-shaped groove for engaging and conforming to the surface of one of the side faces of said slide block, said slide block having a longitudinal recess formed on its upper face, registering with a longitudinal recess formed on the lower face of said slide; a presser plate positioned in said recesses and movea'ole longitudinally therein, said presser' plate having an inclined face engaging an inclined face in one of said recesses and effecting, upon longitudinal movement in one direction, a separating pressure between the lower face of said slide and the upper face of said slide block for pressing the faces of said V-shaped g" 't the side face of the slide block engaging finsaid groove; and means engageable with said presser plate and said slide block for effecting longiti'idina'l movement of said presser plate; a presser block having a V-shaped groove for engaging the opposite side face of said slide block and seated in a recess formed said slide and adapted, upon longitudifialfiiove'ment, for eier'ting a separating presser Between the bot? tom of said last named recess and theenga cd face of said slide block; and means engageable said piess'er meek an said'slideifoi' effectiiig lerigitudinal riioveiiient of said presser block.
